The linear momentum (p) of a body is the product of its mass (m) and its velocity (v), i.e. p=mv. See alsoangular momentum.
Mathematics
Seeangular momentum, linear momentum. Often ‘momentum’ is used to mean linear momentum.
Chemical Engineering
The quantity given by the mass of a body multiplied by its velocity. Used in the study of dynamics, its quantity is conserved under certain circumstances, and its rate of change gives the amount of force acting on the body.
